Thermal Expansion Of Acrylic Sheet

Cast versus extruded acrylic.

Thermal expansion of acrylic sheet.

Perspex cell cast acrylic technical data sheet 1. Thermal expansion can present significant challenges for designers in certain areas for example when constructing spacecraft aircraft buildings or bridges but it can have positive uses. Masking perspex sheet is supplied with double sided non thermoformable masking. The nature of most plastics and the construction of the dilatometer make 30 to 30 c 22 f to 86 f a convenient.

Plexiglas acrylic sheet will expand and contract with changes in temperature and humidity. Allowances must be made for these changes in the construction and fabrication of products.
